removing freewheel w/o freewheel remover?

ive got a wheel that I want to cut apart and use the hub for a project, the wheel has a junk shimano 5spd freewheel on it. none of my freewheel removers will fit it. is there any way I can disassemble the freewheel and get it off without the proper remover? Its no biggie, I can stop by the LBS tomorrow if I have to, I just would like to get it off tonight if I can.
thanks folks

"FREEWHEEL REMOVAL WITHOUT A TOOL 101":
Freewheel removal without the proper tool is a complete mess and a total pain-in-the-ass. Don't do it. Either buy the tool, or bring the wheel to a bike shop and have them remove it (free or maybe a couple of bucks).
